ASHRAE
See American Society of Heating, Refrigeration, and Air-
conditioning Engineers
American Society of Heating, Refrigeration, and Air-
conditioning Engineers
An international organization of 50,000 persons with
chapters throughout the world. The Society is organized
for the sole purpose of advancing the arts and sciences of
heating, ventilation, air conditioning and refrigeration. It
benefits the public with its research, standards writing,
continuing education, and publications.

BACnet
See Building Automation Control network
BACnet interoperability building blocks (BIBBSs)
A block of BACnet application services that tells vendors
what BACnet services must be implemented to provide
specific device functionality. The BIBBs are grouped
together into BACnet device profiles.
BACnet object
An abstract representation of the physical point or points
where data is input from or output to an I/O device. Each
object may have several BACnet properties that describe
the status of that object.
baud rate
The number of signaling elements that occur each second
during electronic data transmission. At slow speeds, baud
indicates the number of bits per second that are
transmitted. For example, 500 baud means that 500 bits
are transmitted each second (abbreviated 500 bps). At
higher speeds, multiple bits may be encoded with each
electrical change.

Building Automation Control network (BACnet and
ANSI/ASHRAE Standard 135-2008)
An interoperable protocol developed specifically for the
building controls industry. The American National
Standards Institute named it as a standard, and Trane
advocates BACnet protocol for use in system-level control
devices.

D
device
A device is a standard BACnet object as defined by
ASHRAE Standard 135-2008. The Tracer UC800 unit
controller contains the BACnet object.
Device ID
The Device ID uniquely identifies each BACnet device and
can range from 0 to 4194302. There cannot be more than
one device using the same Device ID. Each of the sample
applications operate as a device and requires its own
device ID, which defaults to zero.
I
interoperability
The ability to integrate equipment from different vendors
into a comprehensive automation and control system.
Additionally, digital communications between products
designed independently, but designed to the same
communication standard.
M
MAC address
The media access control (MAC) address is the unique
serial number burned into Ethernet and Token Ring
adapters that identifies that network card from all others.
P
protocol
A set of rules (language) that governs the exchange of
data over a digital communications system.
S
stand-alone operation
Equipment is running in a stand-alone mode when all
control is provided by the electronic control system of the
equipment. The system controls the building environment
to a local set of configuration and setpoint values. It
monitors the environmental conditions with sensors that
are physically wired to the control system of the unit.
